Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is mainly applied when a humidifier is used in conjunction with a heat pump type air conditioner for heating.

Conventional configuration and problems When using a conventional heat pump air conditioner for heating, as the room temperature rises, the relative humidity in the room decreases, causing problems if the room becomes too dry.

In addition, in recent years, separate humidifiers have been increasingly used to prevent this dryness, but it is difficult to ideally control the relationship between air conditioning conditions and the amount of humidification, and excessive humidification tends to occur. There was a problem in which a large amount of condensation formed on the walls and windows when the system was shut down and the room temperature dropped.

Additionally, a configuration in which a temperature sensor is built into the humidifier for control has been considered, but the difference in humidity distribution between the vicinity of the humidifier and each part of the room is large, and ideal seven-degree temperature control has not been possible.

Purpose of the Invention The purpose of the present invention is to perform more optimal humidity control during heating, and to organically link air conditioner control conditions and humidifier control, aiming for more comprehensive ideal air conditioning. be.

Structure of the Invention In order to achieve the above object, the humidifier control device of the present invention includes:
A control device is provided that uses a room temperature sensor, a room temperature setting section, an operation switch, and a humidity sensor as input sources and controls an actuator section and a humidifier control section, and this control device includes a first condition section that determines whether the operation switch is for heating or not. , a second condition section that determines whether the temperature detected by the room temperature sensor is lower than the temperature set by the room temperature setting section, a third condition section that determines the previous humidifier operation, and a temperature detected by the room temperature sensor. a fourth condition section that determines whether the indoor temperature is above a predetermined value; a fifth condition section that determines whether the detected humidity of the humidity sensor is below a predetermined value; and a determination at a temperature lower than the fourth condition section. It has a sixth condition part and a seventh condition part that makes a determination with higher humidity than the fifth condition part, and the fourth condition part and the fifth condition part or the sixth condition part and The configuration is such that a seventh condition part is activated, and when the first condition part, the second condition part, the fourth condition part, and the fifth condition part are all satisfied, or the first condition part, the second condition part, and the sixth condition part are satisfied. The configuration is such that the output is turned on only when the condition part and the seventh condition part are satisfied, and the output is turned off when the condition is not satisfied.

DESCRIPTION OF EMBODIMENTS Regarding one embodiment of the humidifier control device according to the present invention, the first embodiment will be explained below.
This will be explained using the control circuit block diagram shown in the figure and the control flowchart shown in FIG.

First, the circuit configuration will be explained with reference to the control circuit block diagram shown in FIG. Here 1 is a microcomputer (
Control device λ2 is a room temperature sensor, 3 is a room temperature setting section, 4 is an operation switch, 5 is a humidity sensor, 6 is a system clock section of the microcomputer 1, 7 is a compressor, a fan motor,
Actuator unit used to control air conditioners such as valves, 8
is the humidifier control section.

The microcomputer 1 uses the room temperature sensor 2, the room temperature setting section 3, and the operation switch 4 as inputs, and uses the actuator section 7 as an output to perform general control of the air conditioner.

In addition, the room temperature sensor 2, the room temperature setting section 3, and the operation switch 4
, the humidity sensor 5 is used as an input, and the humidifier control section 8 is used as an output to control the humidifier.

Next, the operation of the humidifier control device will be explained using FIG. 2.

This figure is a flowchart of the humidifier control part in the air conditioner.

The condition section for determining ○N10FF of the humidifier is configured as follows.

That is, a first condition section that determines whether the heating operation is in progress, a second condition section that determines whether the thermostat determined by the room temperature sensor 2 and room temperature setting section 3 is ON, and the previous humidifier operation. A third condition part that determines whether the temperature detected by the room temperature sensor 2 is T, 'C or more, and a fourth condition part that determines whether the relative humidity detected by the humidity sensor v5 is A% or less. and a fifth condition part for determining.

A sixth condition part that determines whether the temperature detected by the room temperature sensor 2 is T2°C or more, and a seventh condition part that determines whether the relative humidity detected by the temperature sensor is B% or less.
It consists of a condition part.

Here, the temperature measured by the room temperature sensor 2 is T 2 < T I,
The relative humidity detected by the humidity sensor 5 has a relationship of A<B.

Here, if the previous humidifier operation was OFF, the first
, only when the second, fourth, and fifth condition parts are satisfied, and if the previous humidifier operation was ON, humidification is performed only when the first, second, sixth, and seventh condition parts are satisfied, respectively. O the vessel
Let it be N.

Next, each condition part will be explained.

The conditions under which it is necessary to turn on the humidifier are: 1. Under heating conditions, the room temperature is on the rise, and the relative humidity is on the decline from now on. 2. The room temperature is above a certain level, that is, normal. The relative humidity has fallen below the allowable value after heating operation. 3. The relative humidity is actually low.

If we adopt a configuration in which the humidifier is controlled only by relative humidity, 1. There will be variations in the set value due to the distribution of relative humidity. 2. There will be large variations in the setting value when considering humidity sensor variations, temperature characteristics, aging deterioration, foreign matter adhesion, etc. Variations occur 1 3 When the humidity sensor malfunctions, problems occur because there is no guaranteed function.

Therefore, in the present invention, all of the humidifier ON conditions are set as AND conditions to suppress excessive humidification and ensure an appropriate humidifier 1.

Detection temperature and humidity sensor 5 by indoor temperature sensor 2
By providing hysteresis to each setting of the detected relative humidity, chugging of the humidifier output is prevented and more stable humidifier control is achieved.

Effects of the Invention According to the present invention, by using humidification to prevent a decrease in relative humidity during heating, and by controlling it in conjunction with air conditioning conditions, it is possible to always maintain a moderate relative humidity. , it is possible to minimize condensation on the wall when the heating operation is stopped.

In addition, the influence of variations in temperature sensors due to various causes can be minimized, and together with temperature control in air conditioners, this greatly contributes to the realization of ideal air conditioning.

Furthermore, since the feeling of heating is increased by appropriate humidification, it becomes possible to set the room temperature to a lower level, thereby contributing to energy saving.
